#Standalone Host FZ4 :  2010-08-15 13-38-27 Error CheckPasswordPolicyCompliance - Exception while validating service user #password comply with environment policy. : Exception - Microsoft.Ceres.Installers.Products.Fsis.CmdletFailedException: #Inconsistent user profile state detected. This could be as a result if the user profile was manually deleted by using the #command prompt or by using Windows Explorer. A profile that is manually deleted does not remove the security identifier (SID) #from the profile list in theregistry. You should remove the account and optionally delete the SID from the #SOFTWARE/Microsoft/Windows NT/CurrentVersion/ProfileList/. Refer http://support.microsoft.com/kb/947215 for further #information.

#. The other one was related to the content api and search api. I eventually used the following:
#
# esp.sdk.5.3.sp3.contentapi-dotnet2.0patch01.ALL  (content api 5.1.1.61)
#  esp.sdk.5.3.sp3.searchapi-dotnet2.0patch01.ALL (search api 5.3.0.6)
#
#  I successful installed it now. You have to use the Esp-searchapi.dll from the old release package, not from the search api #last patch. The content api files must be from the last patch, as Kathrine said.
#  
#The thing is, clearing the IIS ASP.net cache is very important if you use earlier version of API and failed #the install. (C:/Windows/Microsoft.NET/Framework64/v2.0.50727/Temporary ASP.NET Files)

FSIS post install:
 
#From a powershell window:
#nodememlimit option is required with limited memory,otherwise the interaction engine will failed to deploy
./InstallConfig.ps1 -action I -espSdkDir c:/espsdk -defaultSecurityConfiguration -secureStorageDir c:/fsissecure -nodememlimit 512

Fast Search Designer:
from command line window:
msiexec /i FSIS_Designer.msi
IMS UI Tookit:
Step C: the admin port should keep as 17004,although the admin UI port is 17015
Step D(about the cert which your IMS UI Tookit use to connect to FSIS Engine): don't uncheck,This is not an option,It's mandatory

<think>嗯,用户这次聚焦在F2FS文件系统的Checkpoint机制上,看来之前关于LFS背景的引用只是铺垫。用户可能是文件系统开发者或存储研究员,需要技术实现细节而非概念描述。注意到用户引用中提到了Log-structuredFileSystem(LFS),这很关键,因为F2FS正是基于LFS理念设计的。上次回答快速排序时用户没有追问,这次却深入询问特定文件系统机制,说明技术层级较高,需要提供专业级实现细节。Checkpoint在F2FS中是个复合结构,需要分三部分解释:首先其核心作用是维护一致性,这要对比传统fsync的不足;其次是具体结构组成,包括数据索引和元数据;最后是触发逻辑,这里需要强调区别于ext4的设计哲学。用户可能实际遇到的是checkpoint频繁触发导致的性能问题,或是崩溃恢复异常。虽然没明说,但准备在机制解释后补充典型故障场景:比如fullcheckpoint时系统卡顿,或nestedcheckpoint导致恢复失败的情况。技术要点需要严格对应文档:参考Linux源码的f2fs.h中CP_标志位定义,以及checkpoint.c里关于block分配流程。用户给的邮件组引用[1]正好是f2fs-devel讨论组,其中有篇2013年的线程详细讨论过checkpoint的原子性实现,可以间接佐证。</think> F2FS的Checkpoint机制是其保证**数据一致性**和**崩溃恢复能力**的核心设计,其机制与使用主要包含以下层面: --- ### **一、Checkpoint的核心作用** 1. **一致性快照**:将文件系统的关键元数据(如有效块索引、目录结构、文件属性等)生成一致性快照[^1] 2. **崩溃恢复点**:系统崩溃后可根据最近一次Checkpoint快速重建一致状态 3. **清除脏页**:触发后会将脏数据页(Dirty Page)回写到磁盘 --- ### **二、Checkpoint的触发机制** | **触发类型** | **触发条件** | **特点** | |--------------------|------------------------------------------------|-----------------------------| | **定期Checkpoint** | 按时间间隔(默认60秒) | 减少元数据丢失风险 | | **阻塞式Checkpoint** | `fsync()`/`sync()`系统调用 | 强制同步数据,高延迟保证一致性 | | **空间不足触发** | 当空闲空间低于阈值(默认5%) | 紧急回收空间 | | **卸载卷时触发** | `umount`操作 | 确保卸载时元数据持久化 | --- ### **三、Checkpoint的数据结构** ```plaintext +----------------------+ | Checkpoint Header | --> 包含版本/时间戳/校验和 +----------+-----------+ | +-------------------+-------------------+ | | +--------------+--------------+ +------------------+-----------------+ | Segment Information | | Node Address Table | | - 有效块位图 (Valid Block Bitmap) | | - 存储活动inode的物理地址 | | - 当前段分配状态 | +-----------------------------------+ +---------------------------------+ ``` - **NAT(Node Address Table)**:记录inode号到磁盘物理地址的映射[^1] - **SIT(Segment Information Table)**:段的使用状态位图 - **数据冷热分离**:依据数据更新频率选择写入位置(热数据/冷数据区) --- ### **四、崩溃恢复流程** 1. 加载最近成功的Checkpoint区域 2. 重建NAT和SIT表到内存 3. **重演日志(Roll-forward Recovery)**: - 扫描Checkpoint后的**新日志** - 重做已提交但未落盘的操作 - 丢弃未完成的事务 4. 验证文件系统完整性 --- ### **五、性能优化实践** 1. **异步Checkpoint**: ```c // Linux源码示例 (f2fs_submit_merged_write_cond()) if (need_flush || !is_sbi_flag_set(sbi, SBI_NEED_CP)) f2fs_submit_merged_write(sbi, DATA); ``` 2. **延迟元数据写入**:允许元数据在内存中暂存,减少磁盘I/O 3. **多类型日志分离**:区分为**数据/目录/节点**三类日志,减少冲突 --- ### **六、常见问题处理** 1. **Checkpoint阻塞I/O**: - 调整`/sys/fs/f2fs/<disk>/cp_interval`(默认60000ms) - 增加系统内存(降低脏页回收压力) 2. **空间回收失败**: ```shell # 手动触发Checkpoint回收 echo 1 > /sys/fs/f2fs/<disk>/cp_reclaim ``` 3. **恢复失败检查**: ```shell # 查看Checkpoint状态 dmesg | grep "F2FS recovery" ``` --- ### **典型应用场景** 1. 移动设备闪存(Android默认文件系统) 2. 高吞吐数据库日志存储 3. 容器持久化卷(Cloud-native环境) > ⚠️ **重要提示**:当连续出现"Checkpoint=disabled"日志时,表明文件系统已进入只读模式,需立即备份数据并使用`fsck.f2fs`修复。 ---
